iOS如何将选定的单元格值隔离到另一个视图控制器中

Question

I have a Uitableview cell that has been successfully populated with dictionary array. Right now, i have difficulty passing the selected cell value to another view controller and display that value.

Here is my codes:

- (void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath{


    NSLog(@"Tapped: %@",[[feeds objectAtIndex:indexPath.row]objectForKey:@"IncidentNumber"]);
    someProperty = [[feeds objectAtIndex:indexPath.row]objectForKey:@"IncidentNumber"];
     [self performSegueWithIdentifier:@"item" sender:self];

}
- (void)prepareForSegue:(UIStoryboardSegue *)segue sender:(id)sender {
    // Get the new view controller using [segue destinationViewController].
    // Pass the selected object to the new view controller.
    if ([[segue identifier] isEqualToString:@"yourSegue"])
    {

        DescriptionViewController *vc;
               vc = segue.destinationViewController;

                vc.item_pass = someProperty;
    }


}

Answer 1

您使用标识符项执行segue，但稍后在prepareForSegue ，检查标识符为yourSegue的segue ...

Answer 2

Instead of implementing didSelectRowAtIndexPath connect the segue to the table view cell (rather than to the view controller).

Then the selected cell is passed as sender parameter in prepareForSegue and you can get the index path with

let selectedIndexPath = tableView.indexPathForCell(sender as! UITableViewCell)!
